PERFORATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 678,577, dated July 16, 1901.

Application filed April 24.. 1901.

T0 at whom it may concern.-

Be it known that I, WILLIAM LUKES, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful'lmprovements in Perforating Devices, of which the following is a specification.

, Reference being had to the accompanying drawings, Figure 1 is a front elevation; Fig. 2, a rear view of same; Fig. 3, a cross-section; Fig. 4, a cross-head with hanging journals; Fig. 5, a lever showing open bearings.

Like letters refer to like parts in all of the drawings.

The object of my invention is to provide a perforating device for office use which will be simple, cheap, efficient, and durable for perforating two holes at one operation in commercial and other papers for binding, filing, &c.

To this end it consists of the base A, to which is permanently attached an integral frame-like structure composed of two uprights K K, which are connected at the top by the bar H, having lineal slots D D. Each upright is turned back at the top at a right angle to form a bracket or upper guide 0 C for the punches P P. They are also turned back at right angles at the base, with an ofiset, as shown in Figs. 1 and 3, to form the lower guides for the punches and for fastening the framework to the base, a cross-head G, with two integral hanging journals J J ,two punches P P, and spiral springs N N, and finally a depressing-lever L, with open bearings B B. These several parts, constructed and combined to operate as hereinafter described, embody my improvements and constitute the device. All of the several parts except the punches and springs may be suitably made of cast iron or other molten metal and then with rivets or screws the frame fastened to the base, as shown in Fig. 3. These are the only parts of thedevice which are permanently fastened together. Drill the guides and down through the base for the punches. The punches being made from round steel of about three-sixteenths of an inch in diameter will require no other finishing than cutting to required lengths and drilling a small pin-hole near the top end, as shown in Fig. 2, for stops,

which serve as bearings for the springs to re turn the punches and to prevent them from being forced too far up through the guides. The holes for the punches through the base, as shown in Figs. 1 and 3, serve as the cuttingor female die. These holes may be hushed with' steel, if desired, for durability or finer work. The cross-head, Fig. 4, with the hanging journals, is integral and only requires to be drilled partly through at each end to admit the end of the punches upon which the cross-head rests. (See Figs. 1 and 2.) The punches may or may not be permanently fastened into the cross-head-preferably not.

No fitting or other labor is required upon the lever, Fig. 5. The open bearings thereon will cast sufficiently smooth for practical use. ThespiralspringsNforreturning the punches are plainly shown. Their adjustment and application will be sufficiently explained by referring to Figs. 2 and 3.

The several parts having been made and properly fitted, as described, may be separately japanned, ornamented, or otherwise finished and then combined to operate as fol lows: Pass the punches down through the guides, with the coiled springs in position, and there retain them with the stop-pins. (See Fig. 2.) Place the cross-head G upon the punches and then press them down to the bearing. While thus retaining them, attach the lever by passing the tenons at the end into the slots D D and the open bearings upon the journals. (See Figs. 2 and 3.) Then release the pressure and the perforator is ready for use. The ofiset at the base of the uprights forms openings S, which are inter sected by the punches in their descent and admit of the paper to be perforated being passed in between the punches and the female die. By pressing upon the extended end of the lever, which is loosely confined in the slots at the opposite end, the hanging journals serving as fulcrnmsupon which the 5 lever rotates and is kept in place by the open bearings, the punches are forced down through the paper. Thus the perforating is performed. The lower guides strip the paper from the punches as they are returned by the loo springs.

It should be observed that the simple construction of the various parts of my invention constitutes much of its novelty, as each piece may be completely finished and ornamented. Then because of the hanging journals and open bearings they may be put together without the use of a single tool, and that the pressure of the journals upon the open bearings will force the lever up against the cross-head, thus causing a firm engagement that Will rigidly hold the cross head down upon the punches, and that by depressing the crosshead and punches independent of the lever, the lever first and then the cross-head, the punches may be easily removed.

I am aware that perforating devices with twin punches and a lever for depressing the same have been made and used prior to my invention. Therefore I do not broadly claim such a construction; but

What I do claim as new and as my invention, and desire to secure by Letters Patent,

The combination, in a perforating device, of the frame-like structure, the cross-head G, composed of the main body and the journals J J, the lever L, provided with the open bearings B B, and the punches P P, and springs N N, all constructed and attached to a base substantially as and for the purpose described in the specification and shown in the drawlngs.

Signed at Newark, in the county of Essex and State of New Jersey, this 20th day of April, A. D. 1901.
